Abstract

Measurements of the ARINA instrument on board the Resurs-DK1 satellite (altitude ∼ 600 km and inclination ∼ 70^o, since 2006 till 2016) and the VSPLESK instrument on board the International Space Station (altitude ∼ 400 km and inclination ∼ 52^o, since 2008 till 2013) in low Earth orbits were presented in this report. Both instruments are identical in terms of physical layout. They can measure high-energy protons in the range 30-100 MeV with 10% energy resolution and 7^o angular accuracy. Data analysis was carried out for the total period of proton flux measurement by the instruments. L-B proton distributions in the inner radiation belt (L
